We critically review several recent approaches to solving the two cosmological constant problems. The ‘‘old’’ problem is the discrepancy between the observed value of rL and the large values suggested by particle physics models. The second problem is the ‘‘time coincidence’’ between the epoch of galaxy formation tG and the epoch of L domination tL . It is conceivable that the ‘‘old’’ problem ca...

ABSTILACT: The problem is considered of passing from interpolation data for a real rational trarlsfer function matrix to a ~ninintal skate variable realization of the transfer function matrix. The tool is a Loewner matrix, which is a generalization of the standard Mankel matrix of linear s y s tetn realization theory, and which possesses a decompositioil into a product of generalized observabil...

In the paper it is investigated, under which conditions a time variable state transformation can be used to change a periodic autonomous system realization into a form with constant real coefficients. Conditions for the transformation to be periodic are further considered, and it is shown that the necessary and sufficient condition to meet the conditions is in that two specific matrices must be...

The "procedures" discussed in this paper are of the following type: The statistician makes a conventional decision (in a multiple decision problem). He also provides a statement of the guaranteed conditional probability that his decision will be correct, given the observed value of some conditioning random variable. Various admissibility criteria to relate such procedures are proposed. For exam...

We study the possibilities of spontaneous CP violation in the Next-to-Minimal Supersymmetric Standard Model with an extra singlet tadpole term in the scalar potential. We calculate the Higgs boson masses and couplings with radiative corrections including dominant two loop terms. We show that it is possible to satisfy the LEP constraints on the Higgs boson spectrum with non-trivial spontaneous C...

The SU(3) and hyperfine mass splittings of mesons containing a single heavy quark are computed to one-loop order in chiral perturbation theory with heavy quark spin symmetry. Electromagnetic contributions of order αem are included. The observed values of the mass splittings are consistent with the one-loop chiral perturbation theory calculation. The d− u hyperfine splitting (D∗+ −D)− (D∗0 −D) i...

We present a corpus-based prosodic analysis with the aim of uncovering the relationship between dialogue acts, personality and prosody in view to providing guidelines for the ECA Greta’s text-to-speech system. The corpus used is the SEMAINE corpus, featuring four different personalities, further annotated for dialogue acts and prosodic features. In order to show the importance of the choice of ...

The importance of individual actors in business-to-business relationships has been widely acknowledged. Commonly these are referred to in a process-like manner related to division of work in organisational buying, or they are seen as carriers of values and interactions. In marketing, they are rarely described as representatives of various organisational levels. The purpose of the paper is to di...

good governance is an idea which has many advocates and opponents. from last years of 1980s this term became common. however, there is not any clear definition or description for good governance or even governance. though unanimity on its characteristics is invisible, it is possible to consider eight characteristics for god governance: participation, accountability, transparency, rule of law, r...
